Description
TECHNICAL FIELD
[0001] The present disclosure relates to compositions and methods
for cleansing of keratin-based substrates such as hair. In
particular, the disclosure relates to hair cleansing compositions
comprising an alkyl poly glucoside, a betaine compound, and an acyl
amino acid, wherein the composition is sulfate free.
BACKGROUND
[0002] Consumers of personal care products and cosmetics consider
many factors in selecting products for use. Recently, certain
factors have been a focus of and have driven scientific study and
product development. These driving factors for hair care products
include environmental impact, the extent to which the components
condition hair, and the aesthetic quality of the overall product
including clarity and foaming/lathering. Further, the effort
towards environmental impact awareness is a universal concern and
consumers are increasingly selective about the biodegradability of
personal care products and cosmetics they purchase.
[0003] Hair care products which are sulfate free currently exist on
the market, however, they tend to have certain undesirable
properties such as lack of lathering or foaming, lack of gentle
hair cleansing performance, lack of clarity especially in the
presence of oils and fragrances, and poor overall viscosity.
[0004] In addition, currently available sulfate free hair care
compositions require the addition of emulsifiers, thickeners,
polymers, and/or hydrocolloids in order to stabilize and solubilize
conditioning agents and improve viscosity. There are disadvantages
to using emulsifiers, thickeners, polymers, and hydrocolloids. For
example, alkoxylated emulsifiers can be eco-toxic and the process
of producing them is usually harmful to the environment.
Additionally, common thickeners, polymers and hydrocolloids tend to
bio-accumulate and resist biodegradability, or have a negative
effect on the foaming performance of the product. Thus, it is
desirable to provide a composition which has improved
sustainability and is biodegradable and non-toxic as compared to
traditional shampoo formulations, while maintaining the favorable
viscosity, foaming and cleansing properties.
[0005] Therefore, the present disclosure relates to a hair
cleansing formulation that forms a visually clear cleansing
composition with noticeable improvement in viscosity (gel-like
appearance), stability, and solubility of conditioning agents
without the need for emulsifiers such as alkoxylated surfactants or
polyglycerol esters, thickeners such as glycol esters or glycol
ethers, thickening or stabilizing polymers such as acrylic acid
polymers and copolymers, and naturally-derived gums or
hydrocolloids such as cellulose derivatives, guar or xanthan gums.
Emulsifiers are generally described as ingredients that can be
classified as surfactants but have properties that help form and
stabilize an emulsion consisting of two phases such as
oil-and-water containing phases. These emulsifiers are typically
alkoxylated and have PEG, PPG, or polyglycerol functionalities.
Surfactants are defined as ingredients that have the ability to
modify the interface between two immiscible phases by reducing the
surface tension, and serve a cleansing or detergency function.
BRIEF SUMMARY OF THE DISCLOSURE
[0006] In particular, the composition according to the disclosure
demonstrates superior hair cleansing performance, excellent
clarity, and improved foaming texture and abundance, even in the
presence of oils and fragrance, in comparison to other sulfate free
hair care formulations. Additionally, the compositions according to
the disclosure are classified as "readily biodegradable".
[0007] The present disclosure relates to an aqueous hair cleansing
composition comprising (a) at least one alkyl poly glucoside; (b)
at least one betaine compound; and (c) at least one acyl amino
acid, wherein the composition is sulfate free. In another
embodiment, the present disclosure also relates to the aqueous hair
cleansing composition as defined above, further comprising at least
one surfactant.
[0008] Another subject of the disclosure is a method of cleansing
hair, comprising applying the composition(s) described above to
hair.
DETAILED DESCRIPTION OF THE DISCLOSURE
[0009] The present hair cleansing formulation forms a visually
clear cleansing composition with noticeable improvement in
viscosity (gel-like appearance), stability, and solubility of
conditioning agents without the need for emulsifiers, thickeners,
polymers, and hydrocolloids. Also, the present composition
demonstrates superior hair cleansing performance, excellent
clarity, and improved foaming texture and abundance, even in the
presence of oils and fragrance, in comparison to other sulfate free
hair care formulations. Additionally, the compositions according to
the disclosure are classified as "readily biodegradable". "Readily
biodegradable" is a classification term designated by the
Organisation for Economic Co-operation and Development (OECD) that
determines the speed of biodegradation of an organic chemical
compound. Several testing methods can be used when determining the
biodegradability of a compound. "Readily biodegradable" materials
are tested using the stringent methods set forth by the OECD and a
passing result indicates rapid biodegradation in most environments.
For full information about test methods please see Introduction to
the OECD Guidelines for
[0010] Testing of Chemicals Section 3, July 2003, Organisation for
Economic Co-operation and Development (OECD) available at
http://www.oecd.org/dataoecd/38/2/55984432.pdf.
[0011] "At least one" as used herein means one or more and thus
includes individual components as well as
mixtures/combinations.
[0012] "Conditioning" as used herein means imparting to hair at
least one property chosen from combability, manageability,
moisture-retentivity, luster, shine, and softness. The state of
conditioning is evaluated by measuring, and comparing, the ease of
combability of the treated hair and of the untreated hair in terms
of combing work (gm-in).
[0013] "Clear" or "excellent clarity" as used herein means visually
clear. Clarity of a formulation is measured by the transmittance
percentage of light with a wavelength of 700 nm by UV-Visible
spectrophotometry. "Clear" samples allow for between 90% and 100%
of the light to pass through the formula.
[0014] The term "sulfate free" as it is used herein means that
while it is preferred that no sulfate-containing compound be
present in the composition, it is possible to have very small
amounts of sulfate-containing compound in the compositions of the
invention provided that these amounts do not materially affect at
least one, preferably most, of the advantageous properties of the
shampoo of the invention. In particular, "sulfate free" means that
sulfate-containing compounds can be present in the composition at
an amount of less than about 2% by weight, typically less than
about 1.5% by weight, typically less than about 1.0% by weight,

[0033] Formulation Examples 1-3 above were prepared by combining
and blending the ingredients listed and heating to 50.degree. C.
All of formulation Examples 1-3 are clear, slightly yellow,
gel-like compositions. Clarity of the formulation was measured by
the transmittance percentage of light with a wavelength of 700 nm
by UV-Visible spectrophotometry. Clear formulations allow for
between 90% and 100% of the light to pass through the formula.
Specifically, the clarity of formulation Example 3 is 92.4%. The
viscosity of formulation Examples 1-3 varies depending on the
particular combination of conditioning agents used. In particular,
the viscosity of formulation Examples 1-3 ranges between 1500 cP
and 20000 cP (measured using Brookfield viscometer at 50 RPM using
spindle T-C). Thus, although the present composition can exclude
emulsifiers, thickeners, polymers, and hydrocolloids, the
formulation still exhibits a viscosity in the range of 1500 cP to
about 20000 cP.

provides for very similar attribute qualities as Pureology Hydrate
Shampoo. Specifically, differences exist only in the attribute
categories of smooth hair feel in lather, (rinsing) suppleness,
smoothness, static fly away, and squeaky clean. Thus, although the
present composition can exclude emulsifiers, thickeners, polymers,
and hydrocolloids, overall it still provides similar attribute
qualities as those compositions which include polymers and
emulsifiers.
